Patient's question:
Over the past few days, I've noticed that a six-month-old baby has developed a hard lump in the upper part of the muscle on their left upper arm, where they had a vaccination. It looks normal from the outside, but can be felt with the hand. The shape of the lump is somewhat like a date seed.Doctor's answer:
Dear parent,Based on your description of your child's condition, it is likely a local subcutaneous nodule caused by the vaccination. It is recommended to avoid squeezing it and can be treated with local heat application. Do not worry too much. It is suggested to apply heat locally for 15-20 minutes each day, making sure not to burn your child. Persist with this treatment, and it should gradually absorb in the later stages.
